Spot the difference

I’m making good progress with the 2nd edition. Finished all the re-writing, re-arranging and layout-ing. Now I’m working my way through the linked photo folders, searching for duplicates and accidentally swapped fotos. Came across one accidentally unlinked photo in the photo folder. Can you spot the difference? Same student, but top foto taken 20 minutes later during the lesson.

We all got habits, and usually they don’t change. But here you can see a big difference in where she …. did you find it? That’s why I love these fotos … they let us see things that would have gone unnoticed otherwise.

1st edition almost sold out, working on 2nd edition

To write a book is one thing. To show it to people and sell it, another. I would like to thank everyone who helped with the second, much more daunting task. In this regard, a big „Thank you” to Carole Bucher and Jenni Evans. It’s been five years, and almost all copies of the 1st edition have been sold.

I was asked not to have it go out of print. Therefore I decided to release a 2nd edition. On one hand, printing in China can be cheaper than anywhere else the world; on the other hand, it comes with a considerable up front financial investment, shipping costs, import taxes, and rolling storage fees. Therefore, this time I opt for print on demand with Createspace, an Amazon company. They do a great job with printing and shipping.

On the downside, printing costs are going to be much higher (more than four times per copy), and they require a standard trim-size. Which in turn requires a complete rework of the layout. This means I will have to move and re-layout every sentence down to every single letter, every picture, every speech bubble. But since I have to do that anyway, I decided to update some of the texts as well. In the time between publishing the 1st and 2nd edition I’ve been teaching more than 400 group classes, and I just can’t help rephrasing some things. It will still be same book, but in a new layout, and some things phrased differently. It’s quite a labour intensive task, and I hope I can finish it before November 2015.

Here’s my first version of the new cover and 6*9 inch trim size. What do you think?

Stiffness (protecting the lumbar spine from high loads)

I’m not going into detail about the research of Prof. Dr. Stuart McGill, but I’ll just briefly present a stiffness-related finding. In the field of breakdance.

One of the key findings of McGill’s research is that in a well performing core, the core muscles can become stiff and protect the lumbar spine whenever needed. I’ve been reading and exercising a lot into this lately. Yes exercising. Going on the floor and do workout. 25 minutes every day, 5 days a week, for 8 consecutive months now. My learning is very entertaining as well as improving my skills in my full-time practice as a Feldenkrais practitioner.

Today I found this neat little animated gif:

Look at the first move. Very stunning spring-like action! I extracted the single frames:

And I was particularly interested in frames 18,19, and 20:

Because this shows the extraordinary talent of such a guy: he comes down to the floor with a flexed spine, rolling to the floor. The spine is not loaded. But then, when he get’s up, he stiffens his torso! Thus protecting his lumbar spine from the high load that would otherwise be an injury mechanism. Very fast from relaxed to very stiff. Beautiful to watch, isn’t it?

The origin of bone names

Recently I got interested in medical history. The origins of public health, microbiology, Chinese medicine, and mostly why and when people started to do dedicated physical exercise. Also how this spread from Europe to India and back again – our 18 century contortionist gymnastics are now called “modern posture practice” or one form of “yoga”. For this I indulged into the books of Professor Paul Unschuld, Mark Singleton, Günther Loewit, Karel Lewit and some others.

My question of today was: what names did the ancient Chinese give to the bones of the human skeleton? For this I was reading into the book “Huang Di Nei Jing Su Wen: Nature, Knowledge, Imagery in an Ancient Chinese Medical Text” by Professor Paul Unschuld.

The story behind this question goes like this: I was teaching the Feldenkrais lesson “AY 13 Buttocks”, one of the important lessons to resolve chronic knee and back pain. During the lesson I gave the clue that during the posterior pelvic tilt the pubic bone (in german: “Schambein” which translates to “shame bone”) moves forwards.  One student, 82 yo male, complained: “this surely can’t be called pubic bone, I’m a man!” Of course everybody was laughing and saying that the bones are called the same, no matter man or women. But I was wondering: “Do all human cultures have the same names for human bones?”

However, I could not find any distinct names, other than the word 骨, which means bone, 厥骨 at best (which means “peg” bone). Then I read into the modern names of anatomy in Chinese and was a fair bit disappointed: every bone’s name is more or less a literal translation from Latin or English to Chinese. Even the pubis bone has the name 耻骨, which literally translates to “disgrace” or “shame” bone. Far from such poetic expressions like “jade gate” and not even close to a “heavenly roots bone”. As one might have expected from the ancient Chinese culture.

Anyways. On my research I came across a study aid from the University of Texas Health Science Center called “Bone name cards”. I immediately found that very useful to aspiring Feldenkrais Masters, both students and practitioners. They very neatly give some background on why we call the bones the way we call them. There’s like 18 of these cards. Here they are:

My collarbone is different to yours

For new clients I usually start FI by rolling their head and supporting their shoulders. I usually explain everything I do and notice. Recently I started such an FI and commented “you wouldn’t believe how many different variations of clavicles there are”. My new client was very much amazed by this comment, and said “I didn’t know that there are differences at all!”

You might also find this interesting. Therefore I decided to post a couple of images I found on the internet:

This one I found on a bodybuilding forum. The poster did not give any credit, therefore it’s hard to say who drew it.

This is taken from the Journal of Orthopeadic Surgery and Research. Morphological clavicle groups. Mean shapes of the five morphological groups of clavicles. Daruwalla et al. Journal of Orthopaedic Surgery and Research 2010 5:21

This one I found at the open access biomedical image search archive. It says: Examples of clavicle fixation plates. 70.5 percent of variation between measurements is due to differences in width and thickness at the midpoint as well as length, rather than shape. A further 6.7 percent of variation is caused by differences in the lateral depth and angle dimensions and a subsequent 5.0 percent is due to differences in the medial depth and angle dimensions. Finally, a further 4.2 percent of variation is attributed to the change in width and thickness. These four modes attribute to almost 87 percent of clavicular variation.
